Robert Bragg df1915d957 math: Adds an experimental euler API
This adds an experimental CoglEuler data type and the following new
functions:

    cogl_euler_init
    cogl_euler_init_from_matrix
    cogl_euler_init_from_quaternion
    cogl_euler_equal
    cogl_euler_copy
    cogl_euler_free
    cogl_quaternion_init_from_euler

Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h
